casacore::TableParseUpdate::TableParseUpdate	(	const String &	columnName,
		const String &	columnNameMask,
		const TableExprNode &	,
		Bool	checkAggr = `True`
	)

Construct from a column name and expression.

By default it checks if no aggregate functions are used.

		const String &	columnNameMask,
		const TableExprNodeSet &	indices,
		const TableExprNode &	,
		const TaQLStyle &
	)

Construct from a column name, subscripts or mask, and expression.

It checks if no aggregate functions are used.
